Pick an apple! 
Smarter Parental Controls

If you've been using the parental controls options in Mac OS X to lock your child out of using a particular computer late at night, but would like to employ a more clever technique to limit Internet access, turn to MAC address filtering on an Apple base station.

To do this, launch AirPort Utility, select your base station, and click Manual Setup. In the Access Control view, choose Time Access to turn on MAC filtering. You'll need to enter the MAC address of the particular computer, which (in 10.5 Leopard and 10.6 Snow Leopard) you can find in the Network System Preferences pane: click AirPort in the adapter list, and click Advanced. The AirPort ID is the MAC address.


DiskExpress II/SuperLaserSpool Conflict

Send Article to a Friend

DiskExpress II/SuperLaserSpool Conflict -- Jonathan Feinstein of Shrink2Fit Software has contacted us again to report an oddity that users of DiskExpress II and SuperLaserSpool 3.0 may face.

DiskExpress II, a disk optimization system extension (actually, it's a control panel) from ALSoft puts up a dialog box the first time it runs on your computer during the startup process. Basically, the dialog says, "Please read the manual! Have you read it yet?" and asks the user to acknowledge before it continues. When SuperLaserSpool 3.0, the newly-updated print spooler from Fifth Generation Systems, is loaded, though, DiskExpress II flashes this dialog on the screen and makes it go away unanswered. As a result, DiskExpress II does not load.

Since this dialog box only comes up the first time you start up your Mac after installing DiskExpress II, you can avoid the problem entirely by removing SuperLaserSpool temporarily, restarting the computer, acknowledging DiskExpress II's dialog box, then reinstalling SuperLaserSpool and restarting again. It's likely that this problem won't occur if you've rearranged your extension loading sequence so SuperLaserSpool loads after DiskExpress II, but since it will be an issue only once, temporarily removing SuperLaserSpool is a simpler approach.
